Question

form a quadric polynomial whose zeroes are 7+√5 and 7+√5​

Answer 1

Step-by-step explanation:

x=7+

5

x = 7 - \sqrt{5}x=7−

5

{x - 7 - \sqrt{5}} \: and \: x - 7 + \sqrt{5}x−7−

5

andx−7+

5

(x - 7 - \sqrt{5})(x - 7 + \sqrt{5})(x−7−

5

)(x−7+

5

)

(x - 7) {}^{2} - 5(x−7)

2

−5

x {}^{2} + 49 - 14x - 5x

2

+49−14x−5

x {}^{2} - 14x + 44x

2

−14x+44
